Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states what the tool does without any details on behavior, such as output format (e.g., list of rationals), error handling (e.g., for invalid input), computational limits, or side effects. This leaves the agent with insufficient information to predict how the tool behaves beyond its basic function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
